Objective screening mechanism using paralinguistic cues to enhance current diagnostic on detecting depression is desirable, which resulted in the rise of research on this area. However, to date, there has been no research done using dataset of Malay speakers. This paper presented an acoustic depression detection classification using Linear and Quadratic Discriminant analysis with transition parameters...
Optical tracking method has been largely usedfor medical navigation system in Robotic Image GuidedSurgery (IGS). One of the methods proposed by recentresearcher is to use colour feature as the marker for medicalinstruments detection and tracking. Since IGS system isusing preoperative imaging data set for reference, unintended patient movement can result in major errors. Inthis work, the position for...
As image and video processing applications are leaning towards real-time requirement, the program control for the system must be designed efficiently while taking the processing time factor as one of the main considerations. This paper presents the method of detecting multicolour objects and the processing time comparisons of designed algorithms. Algorithm with multithreading approached is compared...
In the recent years, more studies that aim to make computers understand, experience and respond to affects accordingly through computational models have been widely researched. Although many studies have defined and distinguished the words affect, mood and emotion, such terms are still used interchangeably. Thus, in this study, a systematic literature review was implemented to summarize and evaluate...
The development of Image-guided Surgery (IGS) system as an assistant tool in medical navigation has led to new challenges for researchers to enhance the accuracy of the medical surgery. In IGS, a stereo camera is used to find the position of medical markers and visualize it on the screen of the surgeon. However, the line of sight (LOS) between the camera and the markers causes the stoppage of the...
In this work, a model based on Support Vector Machines (SVMs) classification to identify vessel anomaly behavior has been proposed and implemented. The results are compared to Bayesian Networks (BNs). The real world Automated Identification System (AIS) vessel reporting data is used in this work. The results shows that SVMs can achieve higher accuracy compared to BNs in both memory-test and blind-test...
Most of the existing earthquake (EQ) prediction techniques involve a combination of signal processing and geophysics techniques which are relatively complex in computation for analysis of the Earth’s electric field data. This paper proposes a relatively simpler and faster method that involves only signal processing procedures. The prediction of the EQ occurrence estimation using a combination of singular...
The paper is devoted to supervise method approach to identify the vessel anomaly behaviour in waterways using the Automated Identification System (AIS) vessel reporting data. In this work, we describe the use of SVMs to detect the vessel anomaly behaviour. The SVMs is a supervised method that needs some pre knowledge to extract the maritime movement patterns of AIS raw data into information. This...
During the operation of an FMCW (frequency modulated continuous wave) maritime radar, the system transmits a continuous radio energy with a frequency modulated by a triangular or sawtooth-shaped signal. As a result, the frequency of the transmitted signal varies gradually with time. When the signal is reflected by an object, the received waveform will build up a delayed replica of the transmitted...
Like other radar systems, Frequency Modulated Continuous Wave (FMCW) maritime radar can measure simultaneously the range, velocity, reflectivity and azimuth of targets on the sea. However, compared with conventional pulse radar, FMCW radar has many advantages. It is relatively small and simple, offers high resolution, provides data over wide bandwidths, and is relative inexpensive. On the other hand,...
INDERA is the first Indonesian maritime radar that works using the frequency modulated continuous wave (FMCW) technology. In the surveillance mode INDERA continuously transmits modulated electromagnetic waves to detect targets in the surrounding area. Since the transmitted signal is a continuous wave, INDERA needs only a very small power to transmit its signal. Consequently, the level of signals arrived...
